And why some upcoming major third-party titles aren't coming to Switch.

Through Nintendo's E3 2018 Direct did include several surprise announcements and details, the company has seen some leaks of first-and third-party titles in recent months. With the proliferation of them, it's something Nintendo is disappointed in, as the company is disappointed in, especially as it endeavors to expand and deepen its relationships for the Nintendo Switch.

"You know, as a company, we want to surprise and delight our fans. That's what we live to do," Fils-Aime said. "So when leaks happen, it's really disappointing. We work hard to maintain the confidentiality of our information. In this day and age where everyone has a camera and everyone is looking for their 10 seconds of internet fame, it's really tough. But we try hard, very hard to keep our information confidential and keep leaks from happening."

And though one of the biggest games in the world is now on Switch, its upcoming portfolio doesn't include some of the fall's biggest releases, like Red Dead Redemption 2, Assassin's Creed Odyssey, and more.

Fils-Aime noted Nintendo has "always had great business relationships across the developer-publisher community," and that one factor fans wanting these games on Switch may not be considering is the timing of development and Nintendo's conversations with developers and publishers.

"What's driving their availability [on Switch] is when did we first have the development conversations, how far along are the various teams in their progress, how do we make sure that the game could be enabled for Nintendo Switch," Fils-Aime said.

He noted that developers are seeking a platform to easily include in a development cycle, a large install base of console owners, and active players looking for more. Fils-Aime believes Switch has those, and so timing could be one important factor.
